The purpose of this article is to indicate changes in the perception of terrorist threats and the approach to them on the basis of normative documents defining strategic objectives in the area of security. The focus is on strategic papers in the field of security from 2000 to 2014, on the one hand, and on the other, on the law of 10 June 2016 about anti-terrorist activities. The content of the following normative documents has been analysed with regard to the recognition, combating, and prevention of terrorist threats. The authors focus their attention on: the Security Strategy of the Republic of Poland from 2000, the National Security Strategy of the Republic of Poland from 2003, the National Security Strategy of National Security Bureau, from 2007, and the National Security Strategy of the National Security Bureau from 2014. The implementation of the Polish security policy strategy is contained in four types of activity, i.e. national activities, integration with Western security structures, involvement in international actions to resolve hazardous situations, and cooperation with other international actors in strengthening international stability and security. The discussed strategies were created on the basis of the provisions of the amended Act on the universal obligation to defend the Republic of Poland.
